ACETYLENEF'GAS GENERATOR.

SPECIFICATION forming part of Letters'latent No. 678,389, dated July 16, 1901. Appiimion tied April zo, 1901. serial No. 56,720. No model.)

To a/ZZ whom it may concer-1a.'

Be it known that I, FRED FREDERICK, a citizen of the United States, residing at Omaha, in the county of Douglas and State of lNebraska,have invented anew and useful Acetylene-Gas Lamp, of which the following is a specication.

This invention relates generally to an acetylene generator and lamp, and more particularly to a device of such size and shape that -it can be conveniently carried in the pocket and the burner carried in the hand.

One object of the present invention is to provide a gas generator and lamp which can be easily transported and will serve the purpose of the ordinary lantern.

Another object of the invention is to provide a gas-generating device of such sizeand shape that it can be conveniently carried in the pocket and a supply of gas easily regulated, so as to prevent undue pressure wit-hin the generator.

Another object is to provide a device of this character which can be easily taken apart whenever desired.

With these various objects in view the invention consists, essen tially, of a carbid-holder having a gas tube or pipe leading therefrom, a compressible water-holder arranged above the carbid-holder and having communication therewith by means of a valve-controlled passage, andthe spring-actuated pressing means normally bearing upon the compressible water-holder and adapted to inject or force Water into the carbid-holder whenever the valve is open.

The invention consists also in arranging the mechanism which is referred to Within a suitable case which can becarried in the pocket; and the invention consists,still further, in the peculiar construction of the various parts and the novel manner of arranging the same, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of. this speciiication, Figure 1 is a view showing the practical application of my invention. Fig. 2 is a vertical sectional View of a device constructed in accordance with my invention. Fig. 3

is a detail view of the valve-operating mech-- anism. Figs. 4 and 5 show details of construction.

In carrying out my invention I employ a case or receptacle A, which may be made of any suitable material, but preferably of some non-conductive material. This case or receptacle is open at the top,and located within the case is a carbid-holder B, said holder being provided with a suitable opening through which the carbid can be introduced, said 6o opening being closed by a suitable cap or. cover.v The carbid-holder has a small opening B produced centrally in the top thereof, and a tube C is fitted into the said opening,

said tube supporting the holder D at its up- `per end, said holder being essentially hemispherical in shape for the purpose of receiving a compressible water-holder F., which is preferably made of rubber and provided with athreaded nipple E', whichscrews into the 7o upper end of the tube C, thereby making a tight joint between the compressible waterholder and the tube which leads to the carbid-holder.

A presser-blockF is arranged upon the rub'- 75 upon the ball I employ a series of springs G, 8o

connected at their upper ends to the carbidholder, their upper ends being hooked over the upper edge of the pressing block or body, as most clearly shown at G, thus exerting a constant downward pressure upon therubber ball containing the water.

A valve I-I is arranged in the tube C between the carbid-'holder and water-holder, said valve being operated by means of a stem H', which projects upwardly beyond the upl 9o per end of the case and is provided with a suitable knob or handle H2. The lowerend' Vof the valve-stem is connected to a valve by means of a series of link-joints H3, so that rotation of the stem will serve to rotate the valve, opening or closing the same and permitting Water to be forced into the carbidholder or shut off therefrom, as desired. The various parts of the apparatus being constructed and arranged as herein described roo `andshown, it vis apparent that when the valve-stem is operated to open the valve a quantity of water will be forced from the holder down into the carbid-holder, and acetylene gas will be generated. This gas is carl Within the case, a compressible water-holder red oi through the rubber tube I, which passes out through the top of the case and extends a considerable distance and is provided With a burner K at its outer end, which can be lighted and carried in the hand, thus providing a portable light which can be more easily carried than the oil-lantern now in use and which Will produce a ilaine of far greater brilliancy. By having the valve-stern projected above the case the iioW of Water can be greatly regulated, so that the gas can be generated only in such quantities as can be consumed at once, thereby avoiding any 11ndue pressure Within the carbid-holder. By making the Water-holder spherical in form and seating it in a heinispherical body I am enabled to utilize every portion of the water contained Within the holder and under a considerable tension or pressure, thereby preventing gas from the carbid-holder escaping into the Water-holder.

A device constructed as herein shown and described can be conveniently carried in the pocket and manipulated by one hand, While the burner can be held in the other hand.

Having thus fully described iny invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A portable gas-generator and burner, comprising a case, a carbid-holder arranged supported above the carbid-holder and communicating therewith vthrough the medium of a valve-controlled tube or pipe, the valvestem projecting above the case and connected with the valve, the presser-block arranged upon the compressible Water-holder, and the springs attached to said block for the purpose of pressing it downward, and the gasdelivery tube and burner, arranged as set forth.

2. In a device of the kind described, the combination with a case, of a carbid-holder located therein, a compressible Water-holder arranged above the carbid-holder, the cup in which the Water-holder is supported, the tube or pipe connecting said cup and carbid-holder, the valve located in the tube or pipe, the valve-stem projecting above the case and connected with the valve by means of a series of link-joints, the presser block arranged upon the compressible Water holder, the springs attached to the presser-block and eX- erting constant pressure thereon, and the delivery-tube extending from the carbid-holder and carrying a burner at its outer end, substantially as set forth.

' FRED FREDERICK.
